I like it! Why run that timber up to the roof though?

Ah yes. No doubt another hint at your iron theory. Please explain your theory to us in plain english.

:lol: :lol: :lol: Must be copper cos I'm told the zeo rock is green Cookie what is that coral called?

Getting some nice new growth on this one Found out how to crop too!

That box will work, but can look surprisingly big in your tank. A slightly smaller option that will do a good job is this. Can be purchased at Hollywood for I think 20 something dollars, and will be compatable with your skimmer. https://www.marinedepot.com/md_viewItem ... ct=HG10240

Ha Ha! I saw a thread on Reef Central where a guy sat up at night watching pods in his tank with a torch. Then his girlfriend freaked and got all snaky, he couldn't see why, till she pointed out he'd been watching them for 3 hours. He had no idea it had been that long. Guess she just could not see how someone would watch little white things with a torch for 3 hours :lol:

We have established you are obsessed with iron. But to enable sensible debate, you must tell us what your theory is. If you refuse to tell us your point, no point you bringing this iron thing up all the time. After all, you did say

Cyano undesireable? Well yes, sort of. One thing about cyano is it is actually an excellent absorber of nutrients. If a tank has cyano, rather than try to kill it, if it is regularly syphoned, this will be a great way to remove excess nutrients from the tank, continue syphoning the cyano at each opportunity until the nutrients are gone and the cyano receeds.

Bit of both can happen. Once the nitrogen cycle is completed and the sand bed begins producing nitrogen gas, if there is any cyanobacteria slime on the bed, it can accumulate nitrogen gas as bubbles and you get bubbly cyano slime. If there is no cyano, you will just see the bubbles "fizz" into the water. But once everything is stabilized most of the nitrogen will just diffuse into the water, you won't even see it, and it will diffuse back out of the water at the surface into the air. Great to watch all the stages in our new tanks, as it all starts coming together, yes!

Don't see you produce one either. I'm still waiting for you to produce a paper that proves your theory, that the water in a zeovit tank is so high in iron that it kills the zooxanthellae. All you ever do is reference that study from 1998 on a different zeolite that showed it leached iron. But even then it was not shown there was enough iron in the water to kill the zooxanthellae. You're always saying you back your arguments with research, but you never do. I suspect the reason is because there is no proof of your theory, and never will be.

Sorry Layton I'd have to go with Steve on that, it is always you who brings up your iron theory at EVERY opportunity. Why do I argue? Well I've let it pass a few times, but often it just irks me too much to see you posting this misleading and likely false theory.

First I knew hammers can sting, I've touched mine heaps must have been lucky

Tell me about it! Layton I see you do it all the time. Right on! Right on again! Layton I've just been listening to some old Black Sabbath stuff I dusted off from way back. There's a song used to be one of my favourites they must have met you before they wrote it - "Iron Man" :lol:

I've got a blue coral also, never seen that tip disintegration thing Cookie.

Looking good Duke. Nice bit of coraline on that bottom rock too.

Yes, that's a lovely mixed reef. The guy also has a great writing style, it's an entertaining read. We will all identify with at least some of the things he says.

Ok Thanks guys appreciate you sharing the knowledge / advice. I'll hold back on Woosh, but I do support the concept of what they are doing and will see if things improve for them.

Oh No!! Here I was thinking it was too much iron

Whadayaknow!! Iron thread on Zeovit.com http://zeovit.com/forums/showthread.php?t=3892

They didn't. Does that matter?

Layton, I apologise. After all these months I'm not even sure what your still so upset over. But whatever it was, I'm really, truely, awefully, sorry!

Perhaps Layton it will be simpler if we just deal with one question at a time. Where is the test done on water in a zeovit tank that shows iron content high enough to make corals expell their zooxanthellae?

Thanks for the compliment But your theory is that the high iron content in the water causes corals to expell their zooxanthellae. Are you now retracting and saying it in fact - quote "does not necessarily have to correspond to higher iron content in the water" Is that what you are saying now? A total about face I must say. And I'm still just pointing out the iron content of the water in a zeovit tank has never been tested. So yet again, your theory is not a fact.

Correct. Zeovit sell an iron supplement that can be dosed. It is used to help the corals darken a bit if they are pale, and also to assist growth. Now Layton claims that zeovit releases so much iron that it causes the corals to expell zooxanthellae, and thereby lighten and reveal their hidden colours. But that is clearly wrong because if that were the case, dosing even more iron as a supplement would increase zooxanthellae expulsion even more. But in fact supplementing iron helps darken the corals by assisting zooxanthellae growth, the opposite to what Layton is claiming.

In those pics, I don't exactly see rocks covered in high nutrient type algae. And what appears to be cyano, is in fact a bacterial film that may include cyanobacteria, which used to be caused by an overdose of the old type of zeostart. In fact I'd be fairly confident that the phosphate level in that tank would be smaller than 0.05. A low nutrient tank by most generally accepted definitions. You claimed to have seen "many" zeovit tanks covered in algae and cyano. Where are they?
